To all 'whom it may concern:

Be it known. that I, JOHN JAY YOUNG, of

Chicago, county of Cook and State of Illinois,

have invented certainiImprovements in Steel Tires, of which thefollowing is a specification: l l My invention relates to the use of alayer of wrought-iron or other soft and tough metal, to which steel canbe Welded, combined with cast-steel or chrome-steel, in the constructionof steel tires for such Wheels as are used in locomotion. Thecombination is made in such A a Way that the outside or wearing surfaceot' the tire shall be composed of steel, and either its opposite insideface or its central part shall f be composed of a layer of wrought-ironor other soft and tough metal welded to the steel.

Figure 1 represents a tire with the iron on `the inside `face Figs. 2and 3, are sectional views of suchtires. z Fig. 4 represents a tire withthe iron in the central part. Figs. 5, 6,

and 7 are sectionalI views, showing different positions of iron in thecenter of the tire.

In each of the figures above enumerated, I represents the layer or ringof wrought-iron or other soft and tough metal, and S the steel.

I do not claim the invention of a combination of steel and iron unitedby welding so asto make iron-backed7 or iron-center steel; but

I claim as my invention- The use and application of the combinations,

as aforesaid, in the construction of steel tires for Wheels used inlocomotion, the purpose of such use and application being to strengthen'the tire and prevent its breaking, chipping, or splitting, especiallyit' it be desired to temper -and give a uniform hardness to the tire.
